"The protein-rich residue left after oil is extracted from soybeans."
Extracting the oil leaves behind a concentrated protein meal — cheap and high in crude protein on paper, but soy protein has a weaker amino acid profile for dogs and cats than named animal protein, and it carries the same allergen risk as any other soy derivative. A filler-protein used to inflate the label's protein percentage affordably. Score: 2/10.
A meaningful red flag: an unnamed source, heavy processing into a by-product or digest form, or documented regulatory scrutiny in at least one country. -4 pts deducted.
